Dunno if it matters… No floppy drive (I use USB external one when needed), some old LG DVD-RAM drive that has problems with opening it lately is in the machine for years already, HDD is 320 Gb.
And also the machine is full of dust inside, plus covered with the "film" from the smoke (I'm a passionate smoker and I smoke like a chimney).

If you happen to use laptops or desktop without dedicated GPU card please post if possible what GPU is on the motherboard (or to be more precise if you happen to have the dreadful Intel Integrated Graphics card) and what is the highest OpenGL version supported by your computer.
